Spectra of Particles from Laser-Induced Vacuum Decay

Understand

The spectrum of electrons and positrons originating from vacuum decay occurring in the collision of two non-colinear laser pulses is obtained.

• It displays high energy, highly-collimated particle bunches traveling in a direction separate from the laser beams.
• This result provides an unmistakable signature of the vacuum decay phenomenon and could suggest a new avenue for development of high energy electron and/or positron beams.
